Binary search run time

WebSo overall time complexity will be O (log N) but we will achieve this time complexity only when we have a balanced binary search tree. So time complexity in average case would be O (log N), where N is number of nodes. Note: Average Height of a Binary Search Tree is 4.31107 ln (N) - 1.9531 lnln (N) + O (1) that is O (logN). WebMay 13, 2024 · Let's conclude that for the binary search algorithm we have a running time of Θ ( log ( n)).
